the structural details of these portions of the apparatus forming no part of the invention.

itting the press and blow molds interchangeably are the neck-molds 17, which are so formed as to project over or beyond the press-molds, whereby they may 'be engaged y thtlifting mechanism, which I will new describe. Each of press-molds 6 is preferably mounted on a raised base or stand 18,

secured-to table v5 and which forms a chamber ,or space 18 immediately beneath the mold and within this space isa head 19, which is secured t0 the upper end of a stem 20, depending. through an aperture in the table and into the circular depressed trackway 2' of base 2, stem 20 being preferably provided at its lower end with antifrictionroller 20. Rods 21 p'roject u ward from head 19 and at their up er ends. carry the segmental plates 22, whic are beneath or in line' with the' overhanging portion of the neck-mold when the latter is in position on the blow-mold.

Normally the lifting device is in lowered position, as seenin Fig. 1, and in no wise disturbs the proper relative positions of the press and neck molds. This lowered posi- 1 tion is maintained during the pressing operation, at which'time one of the press-molds is at pressing position or station A, and the arrangement is preferably such that at the same time a blow-mold is in blowing position C, as shown in Figs. 1 and 2. After the pressing operation has been completed and the plunger withdrawn the table is so turned as to place the then active press-mold carrying the neck-mold and freshly-pressed blank to position B. As, this position is approachei'l stem 20 rides upward on an incline 23, placed in the bottom of trackway 2, thereby elevatingr head 19 and plates 22 and causing the latter to lift the neck-mold upward or away from the press-mold, as clearly shown in Fig. 3. This movement is accomplished gradually, or at least not with. the suddenncss which attendsa manual lift, and the lift is in an accurate "or straight upward direction, whereby the blank is disengaged from the interior of the press-mold without injuryr thereto, and with the neck-meld and blank thus 'started or lifted they may be readily transferred by hand to the blow-mold at position C, and by the present adaptation an article may be completed at said position by blowing while another article is being pressed at position A. At each advance of table 5 a 'iblow-mold carrying a completed article is advanced to position D, where it is removed,

vWhile the pressed blank is momentarily at rest at position A pending the advance otV table 5 and while the latter is being advanced there is ample opportunity for the temperature of all portions of the undisturbed pressed blank to become equalized, so that there will be no distorting or thinningtendency when it is started within the press-mold by the gradual and accurate upward movement of the neck -m.old, as above described. Furthermore, this reheating or making uniform of the temp'erature of the glass, combined with the gradual and accurate 4upward movement thereof, results in the elimination of hair and oil marks and other surface imperfections, which are frequently imparted to the glass, owing to their contact with the walls of the mold.

In those adaptations of the invention wherein both press and blow molds are arranged on the same table or carrier, as herein proposed, it will be understood that the molds may be variously positioned with relation to each other and that their number may be varied as circumstances may permit or require, and as the invention relates primarily to the manipulation of the neck-mold subsequent to the pressing operation and preceding the blowing operation it will be apparent that the press and blow molds may be variously arranged either on or in the same organizedY machine or in different machines, as may be preferred.

I claim- 1. The combination of a carrier, a mold mounted thereon and. adapted to be moved thereby toward and from a forming position, a lifting device movable with the carrier and mold, and means cooperating with said device l'or raising the article in the mold as the latter passes from. the forming position.

2. The combi nation of a horiZoiiitally-movable carrier, a mold mounted thereon, vcrtically-movable forming mechanism above the path of movement of the mold, a lifting device mounted on the carrier and positioned adjacent the mold, and means coperating with said device for raising the article in the mold after the latter passes from beneath the forming mechanism.

I5. rlhe combination of a carrier, a mold mounted. thereon, a vremovable neck-mold, and a lifting device mounted on the carrier and pdapted to removably engage the neckniol( 4. The combination of a support, a mold, a

detachable neck-mold, and a lifting device operated from below for removably engaging and elevating the neck-mold.
